STUMP FULLER.

Application filed Kay 15, 1922. Serial No. 561,057.

To all whom it may concern.

Be it known that we, JOHN W. RYDER and WILLIAM O. SKIPPER, citizens of the United States, residing at Enterprise, in the county of Coffee and State of Alabama, have invented a new and useful Stump Puller, of which the following is a specification.

This invention has reference to stump pullers, hoisting drums or the like, the primary object of the invention being to provide a. drum on. which a cable is wound, which cable has connection with a stump or article to be lifted, novel means being provided for controlling the movements of the drum.

Another object of the invention is to provide novel means for throwing the hoisting drum into and out of operation eliminating the necessity of cutting off the motive power to accomplish this result.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is an elevational View of a device constructed in accordance with the invention.

Figure 2 is an end elevational view thereof.

Figure 3 is a plan view of the device.

Figure 4: is a sectional view taken on line 44 of Figure 3.

Figure 5 is an end elevational view of the drum support, and means for operating the drum supporting shaft.

Referring to the drawings in detail, the reference character 5 designates the base of the device, on which are mounted the sup ports 6 which are disposed at opposite sides of the base, and support the bearings 9 in which is eccentrically mounted the shaft 8 which carries the drum 7. Mounted on the shaft 8 are the gears 10 which have teeth 11 disposed at angles to mesh with the worms 12 supported by the shafts 13 that are mounted in suitable openings formed in the inwardly extending walls 14: of the supports 6.

The inner ends of the shafts 13 extend beyond one of the inwardly extended walls ofthe support as shown by Figure 3 of the drawings, where the same are supplied with beveled pinions 15. A bracket 16 is secured to the support and has its inner ends formed with openings to accommodate the shaft 16.

which constitutes the power shaft of the device.

Beveled pinions 17 are secured to the shaft 16, which beveled pinions 17 are in mesh with the beveled pinions 15-to transmit motion to the worms 12. The bearings 9 are formed with squared portions to accommodate the links 18 which have connection with the arms 19 that in turn have connection with the curved portions 20 of the controlling arm 21, one end of the controlling arm extending upwardly and formed into an operating handle 22. Thus it is obvious that due to the construction of the controlling rod, both of the bearings 9 are moved within the supports, and due to the manner of mounting the shaft 8 within the bearings 9, it will be seen that upon partial rotary movement of the bearings 9, the gears 10 may be moved into and out of operation, eliminating the necessity of stopping the machinery to throw the gears 10 into and out of their active positions.

It might be further stated that the links 18 are formed with squared portions 23 to fit over the squared ends of the bearing membersw9, pins 24 being provided to secure the squared ends of the links 18 in position. The controlling arm 21 is secured to the base, as by means of the bearing members 25 and held in position against lateral movement thereby.

The bracket member 16 has its ends positioned in the bearing members 26 which support the shaft 16 as clearly shown by Figure 1 of the drawings. In order that the links 18 will be restricted in their movements, laterally extending pins 27 are provided, which contact with the link members, when the link members are moved to the limits of their upward movements.

A gear wheel. 28 is mounted on one end of the shaft 16, whereby the shaft may be rotated to accomplish the purpose of the machine.

Having thus described the invention, what is claimed as new is In a device of the character described, a base, a shaft supported on the base and extending transversely thereof, beveled pinions secured to the shaft to rotate therewith, relatively short shafts extending at right angles to the first mentioned shaft and carrying beveled pinions meshing with the first mentioned beveled pinions, worms on the relatively short shafts, bearings extending upwardly from the base, a shaft ex tending at right angles to the relatively short shafts and having its ends eccentrically mounted within the bearings, gears on the last mentioned shaft and adapted to be moved into engagement with the worms to receive movement therefrom, said shafts having squared ends. links having squared portions fitted over the squared ends, a controlling arm having right angled extremities, connecting links for connecting the right angled extremities and first mentioned links whereby movement of the controlling arm will move the gears with respect to the worms, and said controlling arms and links being controlled and connected to lock the gears in mesh with the worms.

In testimony that we claim the foregoing as our own, we have hereto afiixed our signatures in the presence of two witnesses.
